Cosmic Sub-Zero - Saturn's satellite can eject blocks of ice into space

Jupiter and Saturn are the two largest planets in the solar system. Their enormous gravitational pull makes their satellites geologically active. In particular, Enceladus, one of Saturn's satellites, can 'shoot' blocks of ice into space.

Here's What We Know

US scientists have been surprised to find evidence of tectonic activity on Enceladus. Its surface is about 0.15% of our planet's surface. Saturn's gravitational pull provokes powerful tremors. They are strong enough to cause the satellite to eject huge blocks of ice into space.

Researchers turned their attention to Enceladus for a reason. It became part of the study along with Ganymede and Europa, two of Jupiter's satellites. Their distinctive feature is the smooth areas around the huge mountain ranges. This was previously thought to be due to fluid exposure, but scientists have come to a different conclusion during the study.

According to the new hypothesis, the force of the tremors is sufficient to cause the debris to be thrown upwards and then slide down the steep slope of the ridge. As the debris rolls off, it gradually flattens the surface of the satellites. Scientists hope that the Europa Clipper spacecraft will be able to confirm their assumptions. It will set off towards Jupiter's satellite on 10 October 2024.
